JOSEPH BENNOH, OE PHILADELPHIA, PENNSYLVANIA, ASSGNOE TO NESBIT D.STOOPS AND JOHN E. MYERS, OE SAME PLAGE.

IMPRVEIVIENT IN SEWING-MACHINE TABLES.

Specification forming part of Letters Patent No. 14L985, dated August19, 18723; application led July 9, 1873.

To all whom it may concern:

Be it known that I, JOSEPH BENNOR, of the city of Philadelphia and Stateof Pennsylvania, have invented certa-in Improvements in Extension-Tablesfor Sewing-Machines, of which the following is a specification;

My invention consists otA sliding bolts ot' peculiar construction, incombination with sockets confined to the lower flat surface ot'thetable-top, and with the extension-cover, so as to holdthe latter inconnection with the top of the table, as hereinafter fully described.

Figure l is a reverse plan of the table top A, having the bolts 0 C andtheir sockets D D in connection therewith. Fig. 2 is a verticallongitudinal section of the top A and cover B, connected therewith bymeans ot the bolts C G. Fig. 3 is a reverse plan view ot' one of thesockets D. Fig. 4t is an isometrical view of one of the sliding bolts Gin areverse position. Fig. 5 is a like view of one ofthe sprin gs E.Fig. Gis aA view of one of the lugs G.

Like letters of reference in all the iigures indicate the same parts.

A is the tabletop of a sewing-machine, and B the cover. C G arel boltsfor connecting the cover -to an end of the top B, as seen in Fig. 2.They slide in the sockets D D, confined, by means of screws, to theunder flat surface of the top A, and are capable of being pushed -backaltogether under the top, as seen in Fig. 1, and of being drawn forwardto support the cover, as seen in Fig. 2. There are springs E E, whoseheels c are held against the under side of the top A, being held inposition by the recesses b b at each Side of the longitudinal Slots cofthe sockets D, (seen in Fig. 3,) without the aid of screws.

The resilient ends of the sprin gs press upon the upper edges of thebolts C C, `and canse the notches d d in their front ends to catch overthe lips e c ot' the sockets when the bolts are pushed back under thetop A, as seen in Fig. l. When the bolts are to be drawn forward forconnecting the cover B with the top, their iront ends are raised fromtheir con nection with the lips c; and when they assume their forwardposition, as seen in Fig. 2, the notches d d are brought, by the actionof the springs E E, over the said lips e c, whereby they are Securelyheld in this position.

The cover B is brought into connection with the top A by pushing it inplace horizontally, the bolts C C passing through the eye-plates F F,confined, by means ot` screws, to the adjacent side -of the cover, theends of the bolts passing under the adjustable inclined lugs G G on theunder side of the cover, and the acute ledges of the lugs resting in thenotches gg of the bolts, whereby the cover is held securely in position.

The lugs are inclined lengthwise, and havev slots h, through whichscrews I pass, and contine them to the under side of the top of thecover B. They are made adjustable for the purpose of regulating thecover to bring its upper surface in line with the top of the table.

I claim as myinventionl. The bolts C C, having notches d d d d and gg intheir upper edges, in combination with the sockets D D, having slots ain their upper sides, and lips c at their front ends, the springs E E,eye-plates F F, and lugs G G, substantially in the manner and for thepurpose above setforth.

2. The adjustable inclined lugs G G, in combination with the cover B andbolts C O, having notches g g, substantially in the manner and for thepurposes above described.

JOSEPH BENNOR.
